About This Workflow
Overview
This n8n workflow showcases how to leverage an AI Agent node to interact with a custom tool. The custom tool, in this case, is another n8n workflow that fetches data from Hacker News. The main workflow uses the On new manual Chat Message trigger to receive user queries, which are then processed by the AI Agent. The agent can utilize the hn_tool (a custom tool defined to call the Hacker News fetching sub-workflow) to answer questions about popular Hacker News posts. This provides a powerful way to create intelligent assistants that can access and process real-time data.
Key Features
- AI Agent for natural language understanding and task execution.
- Custom tool creation for integrating external data sources (Hacker News).
- Sub-workflow design for modular data fetching and processing.
- Manual chat trigger for interactive user queries.
- Data cleaning and stringification for structured output.
How To Use
- Access the Workflow: Load this workflow into your n8n instance.
- Configure OpenAI: Ensure your OpenAI API credentials are set up in n8n.

On new manual Chat Messagenode. - Ask a Question: Enter a query like, "What is the 5th most popular post ever on Hacker News?" The AI Agent will use the
hn_toolto fetch the data and provide an answer.
